KNOW ALL MEN BY THESE PRESENTS:

That I, HORACE R. HAWKINS, of AiiItoN, in the county of Summit, and State of Ohio, have invented certain new and useful Improvements in the Mode of-Turmng Axle-Arms for Carriages, Carts, Horse-Rakes-,-and for similar purposes; and I do hereby declare that-the following is a full, clear, and exact description of the same,

reference being had to the accompanying drawing, forming apart of this specification. v The drawing represents in perspective a turning-lathe containing an axle one arm of which has-been turned according to my improved mode. i

The part marked A represents the frame of a turning-lathe; B, thc'head; C, the tail-block, a nd -D, the

turning-rest. Tofthe spindle which is connected with the head is fastened the face-plate E, having twqgang'el holes a b,-and a driving dog or revolving eccentric centre a. After the pieces of wood or iron have beencnt into proper lengths to form'thc axles, the pieces are placed in the lathe to turn the first -arm F, in doing v'vhieh:

the blank axle should be placed in the lathe, when the gauge-red G is hooked into the hole a in the face-plateE, and care taken that the bottom side H of the axle I is up and crosswise of the stick. After the axle has been properly arranged as above stated, the first arm F is turned to a. suitable size to fit the boxes for which. it is intended, the lathe is then-stopped, and the gauge-rod G is hooked into the hole I) in the face-plate E, which swingsth'e revolving or eccentric driving dog or centre 0 towards the operator, and to the same distance the other side of a vertical or perpendicular line or plane passing through the real centre of'the face-plate that it occupied on the opposite side of said centre when thejaxle was put into turn the first arm;ithe same care being taken to put the axle in bottom side up and level crosswise of the axle. After the axle has been properly arranged, the gauge-hook G is removed, and the turninglof the second arm atthe tail-block of the lathe completed; By the above mode of turning axle-arms, the operation is performed very expeditiously and with great uniformity of pitch and gather. The pitchmay be varied to suit the length of hub anddish of wheel by moving the revolving centre or dog a farther from or nearer to the real centre, while the gatherer may be also changed by moving the revolving dog or centre 0 nearer to or farther from a perpendicular line passing through the real centre, when the blank axle is put in. as above described, the gauge-holes a 6 being so arranged that the dog a will be swung relatively as respects the real centre as described, when the different arms are turned.

By my improved method the arms of iron, as well as wooden axles, can be easily turned, and that, too, upon ordinary wood and iron turning-lathes, when provided with face-plates, gauge-rods, and eccentric or driving centres, as described and shown in the accompanying drawings. My invention renders the work of turning the arms far less complicated than when the work is perforated by the ordinary modes new ih use.

Having described my improvements in turning axle-arms, what I claim therein as new and of my invention, and desire to secure by Letters Patent, is-

The combination with a turning-lathe of ordinary or suitable construction of a face-plate and eccentric or driving centre under such an arrangement that the arm of the axle placed in the machine may be turned with a combined gather and pitch in the manner herein shown and specified.

HORACE R; HAWKINS.
